HOT-COKE CONVEYER.

SPECIFICATION brming part 0f Leiters Patent N0. 732,545, dated June 30, 1903.

Application iiled March 10,1903. Serial No. 147,185.` (No model.)

To a/ZZ whom t may concern,.-

Be it known that I, MAURICE GRAHAM, a subject of the King of Great Britain and Ireland, residing in Leeds, county of York, England, have invented certain new and useful Improvements in Hot Coke Conveyers, of which the following is a specification.

The object of this invention is to provide in a conveyer for the hot coke discharged from the retorts of gas-furnaces means for preventing the escape of steam and objectionable gases from the coke into the adjacent space within the gas-house.

For this purpose the invention consists in the combination, with a retort-setting or plurality of settings, of a conveying mechanism arranged at the discharge end of said setting for receiving the coke therefrom, a housing inclosing said conveyer and adapted to permit the passage of the conveying device therethrough, an exhaust pipe or pipes connected with said housing opposite said retort setting` or settings, respectively, and a fan or fans connected with said exhaust pipe or pipes for drawing oif the noxious vapors and steam arising from the coke within said housing.

The invention consists, further, in certain details of construction and combinations of parts, which will be fully described hereinafter and finally claimed.

In the accompanying drawings, Figure lis an elevation showing the rear or discharging ends of a plurality of retort-settings with my improved conveyer arranged in position for conducting off the coke discharged therefrom. Fig. 2 is a plan view of a portion of the conveyer-chain. Fig. 3 is a vertical transverse section, 011 a'larger scale, on line 3 3, Fig. 1. Fig. 4 is a plan view of Fig. l, showing also the gas-house wall and retort-work in crosssection. Fig. 5 is a vertical longitudinal section, ona larger scale, online 5 5, Fig. 4. Fig. 6 is a side view of a portion of the conveyingchain and one of its supporting-drums; and Fig. 7 is a vertical transverse section on line 7 7, Fig. 6.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A A2 A3 A4 A5 AG indicate retortsettings of the ordinary or any preferred construction.

ay indicates the individual retorts.

The conveying device proper consists of an endless chain B, formed of individual links,

each link having the shape of a grid h and pivotally connected with the next by means of a pivot-pin D', as shown. At the ends of the pivot-pin b are mounted rollers b2, which engage guide-rails b3, suitably supported by bracket-irons b4, whereby the conveyer device proper is supported and guided so as to have longitudinal movement, passing in its travel the several retort settings. The bracketirons b4 are connected with and supported by an exterior housing D, provided with a bottom d, an inner side vwall d', an outer side wall d2, said side walls extending in upward direction, a top e, two channel-irons e e2, and a hinged cover or covers e3.

E indicates transverse I-beams, suitably' cover or top plates of the housing, as shownA in Fig. 2. Below the conveying-chain is arranged a trough formed by two vupright side walls g g. The bracket or channel-irons b4 serve to retain the trough-platesin upright position and tighten the connection of the same with the bottom plate d of the housing, so as to render the trough water-tight.

Spray-pipes 7L h are arranged at the upper part of the conveyer within the same in such position as to direct a spray of water upon the coke being conveyed.

Connected with the outer wall of the conveyer-housing opposite each retort-setting is an exhaust-pipe m. The pipes m may extend independently to any suitable point outside the wall m of the gas-house or may be all connected withone main or trunk exhaustpipe 'm2, which extends to the outside of the gas-house orto any suitable place of discharge. In case the exhaust-pipes m extend directly ICO some point in its length with a suitable fan or suction device m3. In case all the individual or branch exhaust-pipes m are connected to one main exhaust-pipe the latter is provided with a fan m4. For the sake of illustration in Fig. 4 one of the exhaust-pipes is run directly to the exterior of the gas-house, while the remainder are connected to a main exhaust-pipe.

The conveyerchain is supported at each end at a point beyond the conveyer by means of guide rollers or drums n n. The returnpassage of the chain is made outside the conveyer-housing over similar drums'ngn. lhe conveyer-housing is provided at its entrance end with an inwardly-folding iap-door p, adapted to swing in a vertical plane and permit the entrance of the conveyer-ehain in an empty condition. The outgoing end of the convcyer-housing is provided with a similarly-pivoted outwardly-opening flap-door p', adapted to permit the passage in outward direction of the conveyer-chain with the coke thereon. For receiving the coke as the Chain passes over the guide-wheelu, a chute o' is arranged, adapted to discharge into any desired receptacle. For keeping clear of obstruction the trough below the conveyer-ehain in the housing the chain is provided at suitable intervals with depending` push-plates s of approximately the same shape and area as the transverse section of the tro ugh. These plates during the passage of the conveyer pass along in the trough and scrape any obstruction or accumulation of dust or coke therein into suitable discharge-pipes if, connected with the bottom d of the housing and extending to the ground below or to any suitable point of discharge.

The operation of the conveyer will be apparent from the foregoing. Coke from the retorts a is transferred in a highly-heated condition by means of a chute or any other suitable means from the retorts into the passage or doorway between the channel-irons, the doors having been previously opened. rlhe coke falls upon the conveyer-chain, which has a slow forward movement. The discharge having been completed, the doors are immediately closed. The spray from the quench-pipes falling upon the highly-heated coke during and subsequent to the discharge is converted into steam. Noxious gases of various kinds also arise from the coke. The fan or fans connected with the exhaust-pipes are in motion and create a suction through the system of exhaust-pipes, thereby drawing oif the steam and noxious vapors. Exterior air to supply the place of the air and vapors drawn oli' may enter the housing at the ends of the same or through spaces between the doors at the top of the conveyor. rlhe principal amount of air will, however, enter at the doors when the latter are opened during the entrance of the eolie. The escape of steam and noxious vapors during this necessary opening of the doors is overcome by this invention. This useful effect is produced by the powerful draft of the fans,which thereby draw down into the housing and suck away to a proper point of discharge all those noxious vapors and the immense quantity of steam which would otherwise rise and escape into the gas-house when the doors were open for the discharge of coke from the retorts onto the conveyer.

Motion is imparted to the shaft of one of the drums-as, for example, the drum l11.---by means of any suitable mechanism, such as sprocket-and-chain transmission i', from any suitable source of power, (not shown in the drawings,) said shaft u being under such conditions the driving-shaft for the eonveyer and the drum n the driving-Wheel. The fans may be operated by power obtained from any suitable source. All accumulations of dirt, dust, and water in the trough are swept out oi the same by the push-plates into the wastepipes during the movement of the conveyerchain.

lt is obvious that the exhaust-pipes may be connected with the housing at any suitable point of the latter-that is to say, either at the outer side wall, (as shown,) at the inner side wall, at the bottom, or at the top. They may be connected one opposite each retortsetting, or a plurality opposite each setting, or they may be connected opposite alternate settings, as may prove most advantageous .in the particular case, without departing from the spirit of the invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A hot-coke conveyer, consisting of a conveying device adapted to receive and carry heated coke, a housing inclosing said conveying device and adapted to permit the passage of the same therethrough, an exhaust-pipe connected with said housing, and a suction device connected with said exhaust-pipe, substantially as set forth.

2.
